Answer:

Ep = 980 J

Explanation:

First, grams must be converted to kilograms. So, we must divide the value of the mass, by 1000.

  • [tex]\boxed{\frac{10000}{1000}=\boxed{10kg}}[/tex] ---------- Converted to kg.

==================================================================

Data:

  • Mass (m) = 10 kg
  • Gravity (g) = 9.8 m/s²
  • Height (h) = 10 m
  • Potential Energy (Ep) = ?

Use formula:

  • Ep = m * g * h

Replace:

  • Ep = 10 kg * 9.8 m/s² * 10 m

Multiply operations, with units:

  • Ep = 980 J

What is the potential energy?

The potential energy is 980 Joules.
